Door County, Wisconsin

Door County is the easternmost county in the U.S. state of Wisconsin. As of the 2020 census, the population was 30,066. Its county seat is Sturgeon Bay.

It is named after the strait between the Door Peninsula and Washington Island. This dangerous passage, known as Death's Door, contains shipwrecks and was known to Native Americans and early French explorers. The county was created in 1851 and organized in 1861.

Nicknamed the "Cape Cod of the Midwest," Door County is a popular Upper Midwest vacation destination.

Porte des Morts legend
Door County's name came from Porte des Morts ("Death's Door"), the passage between the tip of Door Peninsula and Washington Island. The name "Death's Door" came from Native American tales, heard by early French explorers and published in greatly embellished form by Hjalmar Holand, which described a failed raid by the Ho-Chunk (Winnebago) tribe to capture Washington Island from the rival Pottawatomi tribe in the early 1600s. It has become associated with shipwrecks within the passage. The earliest known written reference to the legend is from Emmanuel Crespel, who termed the peninsula "Cap a la Mort" in 1728.

19th–20th century settlement


The 19th and 20th centuries saw the immigration and settlement of pioneers, mariners, fishermen, loggers, and farmers. The first white settler was Increase Claflin. In 1834, a federal government-operated quarry operation at the mouth of Sturgeon Bay shipped its first stone blocks; they were used for a harbor breakwater in Michigan City, Indiana. In 1851, Door County was separated from what had been Brown County. In 1853, Moravians founded Ephraim after Nils Otto Tank resisted attempts at land ownership reform at the old religious colony near Green Bay. An African-American community and congregation worshiping at West Harbor on Washington Island was described in 1854. Also in 1854 the first post office in the county opened, on Washington Island. In 1855, four Irishmen were accidentally left behind by their steamboat, leading to the settlement of what is now Forestville. In the 19th century, a fairly large-scale immigration of Belgian Walloons populated a small region in the southern portion of the county, including the area designated as the Namur Historic District. They built small roadside votive chapels, some still in use today, and brought other traditions over from Europe such as the Kermiss harvest festival.

Shortly after the 1831 Treaty of Washington, the federal government surveyed what is now Door County to determine the value of the timber and to divide up parcels for eventual sale. Following the treaty, land in what is now the county was sold or granted to private citizens. Lots from 40 to 320 acre were sold at 50 cents an acre. From 1841 to 1932, 1,661 land patents were issued to private citizens. Of these, 774 were bounty-land warrants to veterans authorized by the Scrip Warrant Acts of 1842, 1850, 1852, and 1855. The other patents concerned the sale of land: 711 patents were filed under the Land Act of 1820, 139 patents were filed under the Homestead Act of 1862, and 37 patents were filed under the Morrill Act of 1862.

At the time the Homestead Act of 1862 was passed, most of the county's nearly 2,000 farmers were squatters earning most of their revenue from lumber and wood products. The most common product was cordwood; a cord of maple sold for 37 and a half cents. The remaining portion of the population consisted of about 1,000 fishermen and their families. The fishing industry centered on Washington Island, which at 632 persons was the most populated area at the time. Sturgeon Bay had a population of 230 people. Fishermen caught lake trout and whitefish, which were sold for two cents per pound. Out of the total population of 2,948 people, 170 fought in the Civil War. Most enlisted in 1861 or 1862. The entire assessed valuation of the county that year was $395,000, with an average of $8.00 in tax assessed to each family. It was difficult to earn enough money to pay taxes, which were often delinquent. There were 25 school districts, but staffing was a challenge due to delinquent taxes. Highway 42 between Sturgeon Bay and Egg Harbor had 27 chronic mudholes, some more than 3,000 feet long and passage by wagons was at times unfeasible.

When the 1871 Peshtigo fire burned the town of Williamsonville, fifty-nine people were killed. The area of this disaster is now Tornado Memorial County Park, named for a fire whirl which occurred there. Altogether, 128 people in the county perished in the Peshtigo fire. Following the fire, some residents decided to use brick instead of wood.

In 1883, Harry Dankoler at the Door County Advocate set a world typesetting record.

In 1885 or 1886, what is now the Coast Guard Station was established at Sturgeon Bay. The small, seasonally open station on Washington Island was established in 1902.





As the period of settlement continued, Native Americans lived in Door County as a minority. The 1890 census reported 22 Indians living in Door County. They were self-supporting, subject to taxation, and did not receive rations. By the 1910 census their numbers had declined to nine.

In 1894 the Ahnapee and Western Railway was extended to Sturgeon Bay, with the first train arriving on August 9. In 1969, a train ran north of Algoma into the county for the last time, although trains continued to operate farther south until 1986.

Early tourism
From 1865 through 1870, three resort hotels were constructed in and near Sturgeon Bay along with another one in Fish Creek. One resort established in 1870 charged $7.50 per week (around $160 in 2021 dollars). Although the price included three daily meals, extra was charged for renting horses, which were also available with buggies and buggy-drivers. Besides staying in hotels, tourists also boarded in private homes. Tourists could visit the northern part of the county by Great Lakes passenger steamer, sometimes as part of a lake cruise featuring music and entertainment. Reaching the peninsula from Chicago took three days. The air surrounding the agricultural communities was relatively free of ragweed pollen because grain crops matured slowly in the cool climate and were harvested late in the year. This prevented late-season ragweed infestations in the stubble, which was especially attractive to those with hay fever in the city.

Even after the Ahnapee and Western extended service to Sturgeon Bay in 1894, many tourists continued taking the railroad to Menominee, Michigan to embark on steamships bound for communities in Door County. This route over Green Bay bypassed poor road conditions in the northern part of the county, which persisted until the early 1920s. Only after crushed stone highways were built did motor and horse-drawn coaches become popular for transportation between Sturgeon Bay and the northern part of the peninsula. By 1909 at least 1,000 tourists visited per year, a figure which grew to about 125,000 in 1920, 1 million in 1969, 1.25 million in 1978, and 1.9 million in 1995. In 1938 Jens Jensen cautioned about negative cultural impacts of tourism. He wrote, "Door County is slowly being ruined by the stupid money crazed fools. This tourist business is destroying the little bit of culture that was."

Orchard boosterism
In 1865, the first commercial fruit operation was established when grapes were cultivated on one of the Strawberry Islands. By 1895, a large fruit tree nursery was established and fruit horticulture was aggressively promoted. Not only farmers but even "city-bred" men were urged to consider fruit husbandry as a career. The first of multiple fruit marketing cooperatives began in 1897. In addition to corporate-run orchards, in 1910 the first corporation was established to plant and sell pre-established orchards. Although apple orchards predated cherry orchards, by 1913 it was reported that cherries had outpaced apples.

Cherry crop labor sources
Women and children were typically employed to pick fruit crops, but the available work outstripped the labor supply. By 1918, it was difficult to find enough help to pick fruit crops, so workers were brought in by the YMCA and Boy Scouts of America. Cherry picking was marketed as a good summer camp activity for teenage boys in return for room, board, and recreation activities. One orchard hired players from the Green Bay Packers as camp counselors. Additionally, members of the Oneida Nation of Wisconsin and other native tribes were employed to pick fruit crops. In addition to their pay, Native American families were given fruit that was too ripe for marketing, which they preserved and stored for long term use. A Civilian Conservation Corps camp was established at Peninsula State Park during the Great Depression. In the summer of 1945, Fish Creek was the site of a POW camp under an affiliation with a base camp at Fort Sheridan, Illinois. The German prisoners engaged in construction projects, cut wood, and picked cherries in Peninsula State Park and the surrounding area. During a brief strike, the POWs refused to work. In response the guards established a "no work, no eat" policy and they returned to work, picking 11 pails per day and eventually totaling 508,020 pails.

The Wisconsin State Employment Service established an office in Door County in 1949 to recruit Tejanos to pick cherries. Work was unpredictable, as cherry harvests were poor during certain years and workers were paid by the amount they picked. In 1951, the Wisconsin Department of Public Welfare conducted a study documenting conflict between migrant workers and tourists, who resented the presence of migrant families in public vacation areas. A list of recommendations was prepared to improve race relations. The employment of migrants continues to the present day. In 2013, there were three migrant labor camps in the county, housing a total of 57 orchard laborers and food processors along with five non-workers.

20th–21st-century events
In the fall of 1901, passenger pigeons were seen in Forestville, "in quite large flocks". This is the last reported sighting in the county. Before the forests were cleared away, myriads of passenger pigeons nested in the woods of the Door Peninsula, and during periods of migration they would frequently and effectually cloud the sun in their flight.

In 1905, the Lilly Amiot was in Ellison Bay with a load of freight, dynamite, and gasoline when it caught fire. After being cut loose, it drifted until exploding; the explosion was heard up to 15 miles away.

In 1912, the barnstormer Lincoln Beachey demonstrated his biplane during the county fair; this is believed to be the first takeoff and landing in the county.

In 1913, The Old Rugged Cross was first sung at the Friends Church in Sturgeon Bay as a duet by two traveling preachers.

In 1919, the first Army-Navy hydrogen balloon race was won by an Army team whose balloon splashed down in the Death's Door passage. Two soldiers endured 10 ft waves for an hour before their rescue by a fisherman.

In 1925, a cow in Horseshoe Bay named Aurora Homestead Badger produced 30,000 lb of milk, at the time a world record for dairy cattle.

In June 1938 and again in October 1952, aerial photos were taken of the entire county; in 2011 the 1938 photos were made available online.

On June 14, 1939, Ted Bellak flew his the German-made glider Dove of Peace for 56 mi from the newly opened Cherryland Airport to Frankfort, Michigan. He was towed into the air on a 3/8 in, 200 ft rope prior to gliding independently. At the time, this was the farthest distance traveled in a glider over a body of water. The trip took one hour and six minutes, with 57 minutes spent over Lake Michigan.

In 1941, the Sturgeon Bay Vocation School opened. It is now the Sturgeon Bay campus of Northeast Wisconsin Technical College.

In December 1959, the Bridgebuilder X disappeared after leaving a shipyard in Sturgeon Bay where it had been repaired. Its intended destinations were Northport and South Fox Island. Possible factors included lack of ballast and a sudden development of 11 ft waves. The body of one of the two crew members was found the following summer.

In 2004, the county began a sister cities relationship with Jingdezhen in southeastern China.

To encourage tourism, Ephraim residents passed referendums in 2016 to allow beer and wine to be sold for consumption on premises within the village and to allow beer and single, recorked bottles of opened wine to be sold off-premises. Until then, Ephraim had been the state's last dry municipality.

Geography


According to the U.S. Census Bureau, the county has a total area of 2370 sqmi, of which 482 sqmi is land and 1888 sqmi (80%) is water. It is the largest county in Wisconsin by total area.

In general the shoreline is characterized by the scarp face on the west side. On the east side peat is followed by dunes and beaches of sand or gravel along the lakeshore. During years with receding lake levels, flora along the shore demonstrates plant succession. The middle of the peninsula is mostly flat with some rolling. There are three distinct aquifers and two types of springs present in the county.

The county covers the majority of the Door Peninsula. With the completion of the Sturgeon Bay Shipping Canal in 1881, the northern half of the peninsula became an artificial island. This canal is believed to have somehow "caused a wonderful increase in the quantity of fish" in nearby waters and also caused a reduction in the sturgeon population in the bay due to changes in the aquatic habitat. The 45th parallel north bisects the "island", and this is commemorated by Meridian County Park.

Escarpment and dolomites
Dolomite outcroppings of the Niagara Escarpment are visible on both shores of the peninsula, but cliffs along the cuesta ridge are especially prominent on the Green Bay side, including at Bayshore Blufflands. South of Sturgeon Bay the steep side of the escarpment separates into multiple lower ridges without as many larger exposed rock faces. The face of the escarpment varies in appearance. It may consist of a bare rock face of dolomite alone, or as a face with dolomite above and shale underneath. Sometimes the rock layers are covered with glacial till.

Dolomites in the county have been separated by the different patterns marking the rocks. Each pattern is thought to represent a different general marine habitat from their formation. One layer has relatively straight and flat marks in the rocks, and is accompanied by fossils indicating a tidal flat, especially ostracods. The second layer of rocks has ripple marks and wavy patterns. Since the corals and shells in this layer are broken, the layer is inferred to have formed farther down along the reef shelf, where the corals and shells were exposed to the pounding of the waves. The third layer has rocks full of fossil burrows from marine animals. This layer formed in a still-deeper part of the middle reef under mostly calm conditions. Here, calm waters protected an abundant number of burrowing animals. Along with the fossil burrows are corals, brachiopods, and echinoderms. Yet the rocks in the third layer are interspersed with broken and disturbed material, indicating periodic storms. Each of these three layers is divided into smaller and more detailed sublayers.

The bluffs are interrupted by a series of lowlands which stretch along a northwest to southeast direction; Sturgeon Bay and the Portes de Mortes passage are two of these lowlands. Beyond the peninsula's northern tip, the partially submerged ridge forms the Potawatomi Islands, which stretch to the Garden Peninsula in the Upper Peninsula of Michigan. The largest of these is Washington Island. The islands form the Town of Washington and also the southern part of Fairbanks Township in Delta County, Michigan. The lakebed along the scarp face on the Green Bay side has a sharp bottom gradient, while in many places the lakebed of the Lake Michigan side has a more gentle bottom gradient.

Areas overlooking the scarp face are attractive locations for houses and communications towers, and the stone of the escarpment is quarried. A former stone quarry five miles northeast of Sturgeon Bay is now a county park. Many caves are found in the escarpment.

Shores
The county has 298 mi of shoreline. In 2012, 268 mi of the shoreline along Lake Michigan and Green Bay was surveyed and characterized by type. 42.9 mi of the shore was made of artificial materials, while the remaining 225.1 mi was natural. Of the natural shorelines, 167.8 mi consisted of bedrock and boulders, 39.3 mi was sandy, 17.4 mi were covered in smaller stones such as shingles, pebbles, and cobbles, and 0.6 mi was silty or mucky. Out of the total area surveyed, 101.0 mi consisted of a flat coast, 88.9 mi consisted of 2 to 10 ft bluffs, 68.8 mi consisted of 2 to 10 ft dunes, and 9.3 mi consisted of high bluffs taller than 10 ft.

High points
Eskers are only found in the far southwest corner of the county, but drumlins and small moraines also occur farther up the peninsula. The Door-Leelanau Ridge is an underwater moraine cutting across Lake Michigan between Door and Leelanau counties. A lacustrine terrace is located in Robert LaSalle Park.

The 102 ft Brussels Hill (44.75166°N, -87.59093°W, elevation 851 ft), a crater-shaped impact structure, is the highest point in the county. The nearby Red Hill Woods is the largest remaining maple–beech forest in the area.

Old Baldy (44.92034°N, -87.20192°W) is the state's tallest sand dune at 93 feet above the lake level.

Pollution
The combination of shallow soils and fractured bedrock makes well water contamination more likely. At any given time, at least one-third of private wells may contain bacteria.

Mines, prior landfills, and former orchard sites are considered impaired lands and marked on an electronic county map. A different electronic map shows the locations of private wells polluted with lead, arsenic, and other contaminants down to the section level.

Most air pollution reaching the monitor in Newport State Park comes from outside the county. The stability of air over the Lake Michigan shore along with the lake breezes may increase the concentration of ozone along the shoreline. Additionally, pollution modeling predicts the presence of locally generated air pollution associated with vehicular traffic in the city of Sturgeon Bay.

Soils
The most common USDA soil association in the northern two-thirds of the county is the Summerville-Longrie-Omena. These associated soils typically are less than three feet deep. Altogether, thirty-nine percent of the county is mapped as having less than three feet (about a meter) to the dolomite bedrock. Because there is relatively little soil over much of the peninsula and the bedrock is fractured, snowmelt quickly enters the aquifer. This causes seasonal basement flooding in some areas.

Soils in the county are classified as "frigid" because they usually have an average annual temperature of less than 46.4 °F. The implication of this classification is that county soils are expected to be wetter and have less microbial activity than soils in warmer areas classified as "mesic". County soils are colder than those in inland areas of Wisconsin due to the climate-moderating effects of nearby bodies of water.

Climate
The county has a humid continental climate (classified as Dfb in Köppen) with warm summers and cold snowy winters. Data from the Peninsular Agricultural Research Station north of the city of Sturgeon Bay gives average monthly temperatures ranging from 68.7 F in the summer down to 18.0 F in the winter. The moderating effects of nearby bodies of water reduce the likelihood of damaging late spring freezes. Late spring freezes are less likely to occur than in nearby areas, and when they do occur, they tend not to be as severe.

Attractions


In 1905, Theodore Roosevelt recommended that the Shivering Sands area be protected. Today this area includes Whitefish Dunes, Kellner's Fen, Shivering Sands wetland complex, and Cave Point County Park. Hjalmar Holand, an Ephraim resident, promoted Door County as a tourist destination in the first half of the 20th century. He served on a committee begun in 1927 to protect and promote historical sites, and as a result of this effort the county historical society purchased lands that are now county parks, including Tornado Park, Robert LaSalle Park, Murphy Park, Increase Claflin Park, and the Ridges Sanctuary.

Today, most tourists and summer residents come from the metropolitan areas of Milwaukee, Chicago, Madison, Green Bay, and the Twin Cities, although Illinois residents are the dominant group both in Door County and farther south along the eastern edge of Wisconsin.

Lands open to public use
Door County is home to six state parks. Four are on the peninsula: Newport State Park, northeast of Ellison Bay; Peninsula State Park, east of Fish Creek; Potawatomi State Park, along Sturgeon Bay; and Whitefish Dunes State Park along Lake Michigan. Two are located on islands: Rock Island State Park and Grand Traverse Island State Park. In addition to the nature centers located inside the state parks, there are three others outside the parks. There are four State Wildlife and Fishery Areas and also State Natural Areas that allow free public access. Additionally, Plum Island and the 148.65 acre of Detroit Island within the Green Bay National Wildlife Refuge are seasonally open for public recreation.

Besides county, town, and community parks, there is a boy scout camp, a Christian camp, and a public site operated by The Archaeological Conservancy. A land trust operates 14 privately owned parks open to the public, and 3,277.3 acre of privately owned lands are open to the public for hunting, fishing, hiking, sight-seeing and cross-country skiing under the Managed Forest Program.

Beaches


Including both the Lake Michigan and Green Bay shores, there are 54 public beaches or boat launches and 39 kayak launch sites, leading to the area's promotion as "the Cape Cod of the Midwest". 35 beaches are routinely monitored for water quality advisories.

Although Door County has fewer sunny days than most counties in Wisconsin and Illinois, it also has less rainfall and lower summer temperatures, making for an optimal beach-going climate.

Boating


In 2012, 8,341 registered boats were kept in the county. Most of the county boating accidents reported in 2012 occurred in Green Bay. A 1989–90 study of recreational boating in Wisconsin found that the county's Green Bay and Lake Michigan waters had a higher frequency of Great Lakes boating than any other county bordering Lake Michigan or Lake Superior. The typical motor used in the county's Green Bay and Lake Michigan waters had a horsepower over 90, while the typical motor used for inland county waters had a horsepower under 50. Overall, boaters perceived county waters as uncrowded and boater satisfaction was average.

An annual race is held for which participants build small plywood boats.

The county's longest river canoe route is on the Ahnapee River from County H south to the county line.

Some itineraries connecting the Great Loop around the eastern U.S. and through the Mississippi include stops in Door County.

A charity holds sailing classes each summer. 1972–1973 surveys of high school juniors and seniors in northeast Wisconsin found that students from Door County were more likely to use sailboats than students from other counties.

Lakes and ponds
Besides Lake Michigan and Green Bay, there are 26 lakes, ponds, or marshes and 37 rivers, creeks, streams, and springs in the county. The two deepest lakes, Mackaysee Lake at 26 ft and Krause Lake at 24 ft are on Chambers Island. All streams in the county originate within the county; together they have a combined length of 93 mi, with none more than 15 mi long. The five trout streams have a combined length of 14 mi suitable for trout fishing.

Wetlands
55,124 acres of wetlands cover 18% of the county's land area. 11,400 acres of Door Peninsula Coastal Wetlands are listed under the Ramsar Convention as wetlands of international importance. The listing includes three areas previously recognized as "Wetland Gems".

Recognized natural areas
There are 29 state-defined natural areas in the county.

Living plant collections
Living plant collections include the orchid project at The Ridges Sanctuary in Baileys Harbor and the U.S. Potato Genebank and a public garden in Sevastopol.

Vertebrate species lists
From 1971 through 1976, 11 species of small mammals were found at Toft Point, the Newport State Park Mammals Checklist has 34 species, and in 1972 44 mammals were listed for the entire county. In 1976, 8 amphibians and 7 reptiles were listed as occurring on the Grand Traverse Islands within Door County. In 1978, 8 non-rodent mammals and three squirrels were listed as occurring on the Grand Traverse Islands. From 1981 through 1995, 7 species of frogs and toads were recorded in the county. In 1992 six amphibians and eight reptiles were found in and around Potawatomi State Park. In 1981, nine species of reptiles and amphibians were listed for Chambers Island, and in the summer of 2019 six bat species were acoustically detected on the island.



Unique vertebrates
Tamias striatus doorsiensis, a subspecies of eastern chipmunk, is only found in Door, Kewaunee, Northeastern Brown, and possibly Manitowoc counties. In 1999, the Wisconsin Natural Heritage Inventory listed 24 aquatic and 21 terrestrial animals in Door County as "rare."

Birds
, 166 species of birds have been confirmed to live in Door County, excluding birds seen which lack the habitat to nest and must only be passing through. In 2019, 21 bald eagle and three osprey nests were found to be occupied in the county. In 2013 figures, bald eagles occupied 12 nests and ospreys occupied seven nests.

In 2008 during the spring migration, 13 species of raptors, 19 species of landbirds, and 9 species of waterfowl were seen crossing between the Door and Garden peninsulas. Reverse migration is occasionally observed in the county. When birds traveling north reach the tip of the peninsula and the islands beyond, the long stretches of water sometimes unnerves them. Instead of crossing over to the Garden Peninsula, they turn around and fly back down the peninsula.

During the 20th century, thousands of herring gulls were banded on Hat Island to determine their migratory patterns. Banded birds were found as far north as Hudson Bay and as far south as Central America.

Brood parasitism by red-breasted mergansers has been observed on Gravel and Spider islands and on another island known informally as "The Reef". They laid eggs into the nests of mallards, gadwalls, and lesser scaups.

Rare bees
The sweat bee Lasioglossum sagax was collected on Ridges Road in 2006. Aside from a single collection from Manitowoc County in 2005, it had previously been found only in Colorado.

The kleptoparasitic bee Stelis labiata is considered very rare. It was collected at Toft point in 2006. This was only the second time the species had been found in Wisconsin; the earlier collection's county of origin is unknown.

Horseshoe Bay Cave invertebrates
In 2014 an invertebrate survey of Horseshoe Bay Cave found an apparently groundwater-dwelling amphipod of the genus Crangonyx. Groundwater-dwelling Crangonyx species had never been documented in Wisconsin before. A springtail of the genus Pygmarrhopalites (a genus name synonymous with Arrhopalites) was "found on the surface of drip pools." It appeared to be adapted to cave life and the study concluded that it "could represent an undescribed cave species."

Toft Point invertebrates
In 2004, an invertebrate species list for Toft Point was published listing five isopods, four millipedes, six daddy longlegs, and 113 spiders. Of these, two of the millipedes and 14 of the spiders had never been documented in Wisconsin before.

Spiders
The climate may allow for the better survival of the northern black widow spider.

Additionally, the county is home to the fishing spider Dolomedes tenebrosus, which can grow to about 3 inch, half the size of a tarantula.

Other invertebrates
Kangaroo Lake State Natural Area has the largest breeding population of the endangered Hine's Emerald Dragonfly in the world. Motor vehicles kill an estimated 3,300 of them in the county each year. In 2019, it was reported that out of 14 Hine's Emerald Dragonflies taken from nine locations within the county, all had the same haplotype, indicating a lower degree of genetic diversity. The dragonflies had been caught in the 1990s for other research.

The Lake Huron locust lives on dunes in the county and is not found anywhere else in the state.

From 1996 to 2001, researchers identified 69 species of snails in the county, including rare species.

Research on apple maggots infesting cherries in Door County contributed to the study of sympatric speciation in the 1970s.

In the 20th century, seven fish parasites were found in Hibbards Creek and 13 in Sturgeon Bay.

During an experiment an estimated several thousand Mayflies hatched in Sawyer Harbor in 2016. They had previously been extirpated.

From April to September 2016, 43 species of insects were found to pollinate 26 species of plants near the Sturgeon Bay Ship Canal.

Bryozoans have been noticed clinging to piers.

Springtime


Maple syrup production was 983 gallons in 2017 from seven operations. This was similar to figures from 2012, but down from 2007 when 15 operations produced 2,365 gallons.

The sucker run, which was a popular fishing event in the 19th century, occurs in March and April. Suckers may be taken by frame dip nets, and the sucker run is also sought out as viewing opportunity. Another permitted method of fishing for suckers is by speargun. In April 2018, the state speargun record for longnose sucker was taken by out of Door County waters on the Lake Michigan side. It weighed 3 lb and was 21.25 inch long. In April 2020, the all-methods state record for longnose sucker was caught out of Shivering Sands Creek. It weighed 3 lb and was 22.25 inch long.

Another attraction is mushroom hunting on public land. Additionally, there are two commercial mushroom operations.

Summer
In 2017, there were ten operations growing 14 acre of strawberries.

In 2017, there were eight operations harvesting 5 acre of fresh cut herbs, up from 4 acre in 2012. Two of these operations grow lavender on Washington Island.

In Baileys Harbor, religious tourism includes the Blessing of the Fleet.

Door County has a history of strawberry, apple, cherry, and plum growing that dates back to the 19th century. Farmers were encouraged to grow fruit on the basis of the relatively mild climate on the peninsula. This is due to the moderating effects of the lake and bay on nearby land temperatures. U-pick orchards and fruit stands can be found along country roads when in season, and there are two cherry processors.

However, the cherry and apple businesses have declined since peaking in 1941 and 1964 respectively due to concerns about pesticides, lack of migrant labor and a difficulty in finding local help, the closure of processing plants, unpredictable harvests, the introduction of Drosophila suzukii, land-use competition with tourism and residential development, better growing conditions to the east in the fruit belt, such as the nearby Traverse City area, and intentional destruction of a portion of the crop ordered by the processor in order to drive up prices. In 2017, there were only 1,945 acre of tart cherry orchards, down from 2012 when there were 2,429 acre.

Lightning bugs become common by the end of June.

Fall
Additionally, there were 400 acre of apple orchards in 2017, down from 468 acre in 2012. In 2017, there were 12 acre of pear orchards, spread among 11 operations. In 2017, there was only 1 acre of plum orchards, spread among four operations. In 2007, there were 2 acre of apricot orchards, spread among six operations. Research on the development of cold-hardy peaches has continued since the 1980s. In 2012, there were two acres of peach orchards, spread among seven operations.

In 2017, there were 40 acre of vineyards, down from 78 acre in 2012. The county was recognized as part of a larger federally designated wine grape-growing region in 2012.

In 2021, a county total of 3,940 deer were killed as a total of all deer hunting seasons, up from the total harvest of 4,166 deer in 2020. In 2020, the county had the 6th highest deer density in the state with 56 deer per square mile of habitat.

Another autumn activity is leaf peeping.

Winter
Winter attractions include ice fishing, sledding, cross-country skiing, camping, broomball, pond hockey, snowmobiling, watching lake freighters in Sturgeon Bay, and Christmas tree farms. In 2017, 860 Christmas trees were cut, down from 1,929 in 2012. The county has a white Christmas nearly 60% of the time.

Lighthouses and historical sites
Including both Lake Michigan and Green Bay shorelines, there are 50 total lights and lighthouses, besides lighted buoys. Out of these, there are 10 historically significant lighthouse structures and sets of lights still serving as navigational lights.

Politics
From May through August 2019, a randomized study asked 313 beachgoers visiting 27 Door County beaches and 85 beachgoers visiting three beaches in Algoma, Kewaunee, and Manitowoc which political party they belonged to. Out of the total 398 people surveyed, 38.4% were Democratic, 26% Republican, 19.6% Independent, 1% Green, 1% Libertarian, 2.2% Other, and 11.8% gave no response.

The county has voted more moderately Republican than nearby Brown, Kewaunee and Manitowoc Counties ever since 1940, only voting for a Democrat in 1964 and 1996. In addition, the county has voted for the winning candidate in every presidential election since 1996. President Clinton was the last candidate to win the state without carrying Door County in the 1992 presidential election.

Up until the 2022 Wisconsin gubernatorial election, Door County had voted Republican since the 2010 gubernatorial election.
